摘要：

The paper reports the development of a RF ion source-based transportable compact neutron generator and its application in detecting special nuclear material using the differential die away approach. We present experimental results for the detection of nuclear material in a low-density metallic matrix using an in-house developed 14 MeV (D-T) neutron generator. We have used multi-linear regression for accurately determining the quantity of fissile material even with a small data set.
